Yucca is a genus of shrub and tree in the family Asparagaceae, native to arid parts of North, Central and South America, as well as the Caribbean. There are around 50-60 species of Yucca, recognisable by their evergreen, sword-shaped leaves and large white flowers.

The plant is known colloquially in the American Midwest as ‘Ghosts in the graveyard’, as it is commonly found growing in rural graveyards, appearing as a floating apparition when the flowers are in bloom.
